Clamp



Patented Sept. 27, 1932 UNITED STATES JAMES S. MILLER, OF TRENTON, NEWJERSEY CLAMP Application led February 1, 1930. Serial No. 425,267.

'Ihis invention relates to dental chairs and more particularly to anattachment for holding the paper towels which cover the headrest of thechair.

The principal object of the invention is to provide a device of thisnature for holding a towel used for covering a head-rest which caneasily be attached to a dental chair without alteration thereof.

Another object of the invention is to provide a device of thiskind'having means for resiliently gripping a paper towel used forcovering a. head-rest which can be attached to any make of dental chair.

Other objects of the invention will appear as the disclosure progresses.It is obvious that the actual needs of manufacture may necessitatecertain mechanical changes. It is therefore not intended to limit theinven- 2@ tion to the embodiment illustrated but rather to define suchlimits in the appended claim.

For a more general understanding of the invention attention is called tothe drawing.

In the drawing like reference characters 25 denote like parts throughoutthe specification.

Figure 1 is a side view of a dental chair with the device attachedthereto.

Figure 2 is an enlarged side view of the attachment.

Figure 3 is a longitudinal cross section of the device.

Figure 4 is a top view of the attachment.

Figure 5 is a section on line 5-5 of Figure 4.

Figure 6 is a view of the paper towel.

Referring now to the drawing in detail, numeral 1 designates the dentalchair and 2 a horizontal arm for supporting the headrest 3. Fastened tothe arm 2 is a clamp 4 4o for holding a paper towel 5 by the end 6. rlhebody of the towel is adapted to cover the head-rest while the end 7 isadapted to curl underneath as shown in Figure 1 so it will not interferewith the patients body.

The clamp 4 includes a support 8 having a rounded interior portion 9which ts around one half the horizontal arm 2 and a hinged member 19hinged on a pin 11. The member 10 also has a rounded interior portion 5012 which lits around the other half of the horizontal arm 2. Forfastening the members together a wing nut 13 is provided.

Fastened to the support 8 at an angle is a clip 14 consisting of twogripping members 15 and 16 and a torsion spring 17 for normally holdingthe ends 18 and 19 of the gripping members together. As noted in Figure3 the forward ends 18 and 19 of the clip are curved downwardly so as notto grip the paper towel too sharply at one point and thereby tear same.Also the sides 18 of the upper member lextend downwardly and below thesides 19 of the forward end 19 of the lower member. Numeral 20designates a pair of ears integral with the gripping member 15, and 21 apair of (3o-operating ears integral with the gripping member 16. Theseears are hinged on a pin 22 so that the ends 18 and 19 can be opened bypressing together the opposite ends.

It will thus be seen that I have provided a simple, inexpensive andefficient means for retaining a towel on a head-rest of a dental chair.The device can be attached without any alteration of the chair whateverand does not interfere with the work of the operator.

Having described my invention, I claim: In a clamp of the classdescribed, the combination of upper and lower members pivotallyconnected together, the forward end of the lower member being curveddownwardly, the front and sides of the forward end of the upper memberbeing curved downwardly, the said downwardly curved sides of the uppermember extending below the sides of the said forward end of the lowermember. In testimony whereof I affix my signature.

JAMES S. MILLER.
